A comparison of HIV/AIDS knowledge among high school freshmen and senior students.

Statistical data show that heterosexual transmission of AIDS among teenagers is a significant problem. The purpose of this study was to assess and compare the level of knowledge concerning HIV/AIDS among high school freshmen- and senior-level students and to determine the association between certain demographic variables and the students' knowledge level. A convenience sample of 169 freshmen and 274 senior high school students were surveyed at a local area high school (N = 443). A 49-item knowledge questionnaire, used by the high school district HIV/Abstinence program, and a demographic questionnaire developed by the investigators were used to collect the data. The findings revealed that both the freshmen and senior students had several misconceptions about HIV/AIDS, including the modes of transmission, the sure way of preventing the sexual transmission, donating blood, and the usual causes of death for people with AIDS. A comparison of the mean knowledge scores among freshmen and senior students indicated there was no significant difference among the two groups. The mean knowledge score of the seniors was significantly affected by whether they had received HIV/AIDS education. However, this was not the case for the freshmen. African American students, especially the female students, had significantly lower knowledge scores than other ethnic groups.
